The major problem is that both do not hold charge. I need to charge daily and usually turns off at the end of my daily 8 mile commute. The duration is not even close to the published times and I've tried different chargers, etc. I'm returning both.
I can't comment on the battery life because I've only taken it on short rides so far, but I will note that the USB charging functionality, while convenient, has me a little skeptical. After a full charge, the battery light on the Blinder will turn green, but if you turn on the light and quickly turn it off and then try charging it again, you'll find that the battery light goes red (indicating that it is charging) again. This would be normal if it weren't for the fact that it takes a long time for the charging light to go green again. For now, I'll assume that it's an indicator issue, as the battery couldn't possibly drain so much from turning the light on for a single second.
Knog customer support is awesome, although I think there might be a lost in translation thing going on. I didn't fully secure the bolt under the strap to the light, needless to say it went flying off of my bike. I lost the bolt. I contacted Knog, a day later they replied and said they would send me a replacement. No questions asked, no receipt needed, they paid for postage. I expected to receive a bolt. a few weeks later, I received a full new mount and some straps, which was great but no little bolt included. I contacted them again, and a few weeks later I finally received the small bolt. Anyway, no fuss, great customer service.
The only complaint I have is the awkward charging of the light. They include a few weird little usb cables, and conversion cables. The cable included is super short and doesn't really work in any of my computer USB situations. I typically charge this with a Jawbone wall charger, but the weight of the light will usually make the light fall out. I need to come up with a better way to keep this constantly charged.
Look no further. This is the one you've always needed.
The clasp mechanism is terrible for a couple reasons: it's not centered under the light, so it's front-heavy and nose dives if you hit a bump on the road (the problem is far more disastrous if you go out on the trails) being that there are different sizes for different diameter bars, I forced the smaller one around my bar hoping the additional tension would hold it in place. What instead happened was that the plastic clasp broke off. While knog does sell replacements for cheap, I've broken 2 of them so far. Yet another issue is that the clasp dated by means of a magnet. The magnet is cheaply glued in and falls out quickly. I've thus far kept a magnet in place, but I had to gorilla glue it in place myself after it fell out. As you might have guessed, I've had the light fall off my bars a couple times.
The electronics are also suspect: I've had mine shut off entirely when I've hit bumps. I was following a friend down a trail when it shut off and I had to glue myself to his back wheel (his light didn't malfunction) for the remainder of the very scary descent.
The light also doesn't hold a charge. I've used it for a quick 10 minute run to the store, turned it off and when I turned it on again the next day, the low battery light went on within 15 minutes.
I don't trust this light and I can't return it, so it's been relegated to helmet use only with a different light on my bars. It's a shame because it's a cool looking light and puts out a nice beam when it's behaving. I just can't trust it. Mind you, I bought this light as soon as it was released, so hopefully they've made some changes to the design

Actually this has a very nice shine but you can only use it for 20 minutes on a smooth surface. If you hit a bump it cuts out, it can't be trusted if you ride when it is dark.Published 11 months ago by Shawn Rupert
